FAST Viscometer

Fast Viscometer

The AMETEK Brookfield FAST system has a rugged design with non-moving parts. It has been designed to perform day after day under the extreme demands in printing, coating and adhesive operations - with no maintenance.

Utilizing a high frequency, micro-rotational core, which is unaffected by press vibration, this worry-free system can measure and control the viscosity of your inks, coatings and adhesives from start to finish...allowing the operators to handle other press concerns.


  • Unique micro rotational sensor
  • No moving parts, no maintenance
  • Unaffected by external vibration
  • Flexible vertical or horizontal installation
  • True temperature readings to 120°C
  • Maintains correct color throughout the process
  • Compact: only 8.5 inches tall
  • Worldwide support
